A total of eight people including four children were rushed to Dumfries and Galloway Infirmary after the three-vehicle crash.

Doctors say the injuries of a 29-year-old woman, who was driving the camper van, are causing concern.

Two male passengers in the camper van, aged 21 and 30, have broken bones.

Of the four children, a seven-year-old boy has a kidney injury, while a girl aged six and two boys, aged four and 13 months, have only minor injuries. All of them were travelling in the camper van.

All of the occupants of the camper van are from Dungannon in Co Tyrone, Northern Ireland.

The 57-year-old lorry driver is from Co Monaghan in Ireland. He was not injured and did not need to go to hospital.

A spokesman for Dumfries and Galloway Constabulary said: "We are appealing for any witnesses who may have seen the crash to get in touch."

The road has now reopened.

Three-week-old Oliver Hewson was killed in an accident on the A75 in March. Further pressure was put on the Scottish Government to fund improvements after years of campaigning and recently it was annoucned that two miles of new road will be built between Hardgrove and Kinmount at a cost about £20million.
